Hi all,
Is there a way to speed the following query up?
SELECT APP_DATETIME as LAST_APPOINTMENT, APP_SERVICEID as LAST_SERVICEID
FROM APPOINTMENTS APP1
WHERE APP_DATETIME = (SELECT MAX(APP_DATETIME)
FROM APPOINTMENTS APP2
WHERE (APP2.APP_INVITEDID = :PersonID) AND (APP1.APP_INVITEDID= :PersonID))
Or is there another, better way to find the same information
Thanks in advance,
Tom.
